WILLI is a Cosmic Rays (CR) experiment built in the National Institute for Physics and Nuclear Engineering- Horia Hulubei for studying of the charge ratio and flux of atmospheric muons.

The members of the Cosmic Ray Group in NIPNE are operating the WILLI detector, which has been constructed, set up and extended with the help of KASCADE members (Forschungszentrum Karlsruhe). WILLI is continuously under development and new features are integrated to the detector.
